A research team from the Faculty of Physics of Lomonosov Moscow State University stretched acicular diamond crystallites using an electric field. Deformation occurring during the stretching causes changes in the luminescence spectrum. This effect can be used to develop electric field detectors and other quantum optic devices. The work was published in Nano Letters....

Researchers at The Ohio State University Wexner Medical Center have shown - for the first time - that special bandages using weak electric fields to disrupt bacterial biofilm infection can prevent infections, combat antibiotic resistance and enable healing in infected burn wounds. The dressing becomes electrically active upon contact with bodily fluids. ...

A new technology may make your clothes part of the internet of things (IoT) network. However, unlike other IoT devices, these smart fabrics arenâ€™t dependent on electricity.
Instead, these fabrics use a special kind of conductive thread, which can function without any added electronics. Simply put, while these clothes can serve as data storage, they can also be washed, dried and ironed like regular clothes. ...

Applying an electric field to water in a naturally occurring protein substantially boosts the flow of the liquid and opens up the possibility of delivering more efficient water treatment technology, according to a study co-authored by UCD academics. ...

Scientists have used magnetism to activate tiny groups of cells in the brain, inducing bodily movements that include running, rotating and losing control of the extremitiesâ€”an achievement that could lead to advances in studying and treating neurological disease. ...

Hall thrusters (HTs) are used in earth-orbiting satellites, and also show promise to propel robotic spacecraft long distances, such as from Earth to Mars. The propellant in a HT, usually xenon, is accelerated by an electric field which strips electrons from neutral xenon atoms, creating a plasma. Plasma ejected from the exhaust end of the thruster can deliver great speeds, typically around 70,000 mph. ...

Producers of processed lithium â€“ an essential element for batteries used in electric cars â€“ are agreeing long-term contracts with their customers to fund the investments needed to address a looming shortfall.
Demand for battery-grade lithium compounds is expected to skyrocket in the next decades in tandem with soaring demand for electric cars as governments and individual consumers try to reduce their carbon footprint.
Although thereâ€™s plenty of lithium around, the problem is ensuring there is enough capacity to process it.
Battery m... ...

Queenslandâ€™s State Government has announced that it will be constructing a $3 million network of vehicle charging stations along the East Coast, hoping to incentivise the use of electric cars in the region.
Steven Miles, the stateâ€™s aptly named Minister for Roads, has said that while â€śthe project is ambitious, we want as many people as possible on board the electric vehicle revolutionâ€ť. Currently, the state has a relatively low uptake for electric vehicles, with only around 700 on the roads at present.
A total of 18 charging station... ...

Washington State University physicists have found a way to write an electrical circuit into a crystal, opening up the possibility of transparent, three-dimensional electronics that, like an Etch A Sketch, can be erased and reconfigured. ...

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel's Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X. ...

A batch of single-cell protein has been produced by using electricity and carbon dioxide in a joint study by the Lappeenranta University of Technology (LUT) and VTT Technical Research Centre of Finland. Protein produced in this way can be further developed for use as food and animal feed. The method releases food production from restrictions related to the environment. The protein can be produced anywhere renewable energy, such as solar energy, is available. ...

Both smartphones and electric cars are powered by batteries using similar technologies. But as you can imagine, the scale of batteriesÂ used in electric cars is much biggerÂ than the ones used in smartphones, and these are charged using bigger electrodes calledÂ supercapacitive electrodes.

Used electric vehicles are an amazing value for the money right now. With the market for new EVs showing record sales, it's perhaps easy to forget that some of the best buys are on the used market. A press release reports thatÂ the overall used market for electric vehicles has increased 7% this year in the
Used Electric Vehicle Best Buys (UK Version) was originally published on CleanTechnica.

(Phys.org)â€”A pair of researchers at Brown University has found that it is possible to induce a drop of fluid to emit smaller droplets in a way that resembles the planet Saturn with its rings. In their paper published in the journal Physical Review Letters, Quentin Brosseau and Petia Vlahovska describe the path they took to discovering the interesting droplet formations and possible uses for them. ...

Electric fields can be used to guide neural stem cells transplanted into the brain towards a specific location. The research, published July 11 in the journal Stem Cell Reports, opens possibilities for effectively guiding stem cells to repair brain damage. ...

Researchers at the University of Illinois at Urbana-Champaign and Princeton University have theoretically predicted a new class of insulating phases of matter in crystalline materials, pinpointed where they might be found in nature, and in the process generalized the fundamental quantum theory of Berry phases in solid state systems. What's more, these insulators generate electric quadrupole or octupole momentsâ€”which can be thought of roughly as very specific electric fieldsâ€”that are quantized. Quantized observables are a gold standard in c. ...

It's been a big 2017 for the iPhone. Marking the 10th anniversary of the original iPhone, we were treated to not one, not two, but three new iPhones this year. As well as the usual annual iterative updates of the iPhone 8 and iPhone 8 Plus, the iPhone X became Apple's biggest, flashiest, fastest and, yes, priciest iPhone ever made.
You've come to the right place if you're looking to track down the very best deals on these new iPhones. TechRadar's handy price comparison tool allow you to search for the cheapest deals on all current iPhon... ...

This week is Cleantech Talkâ€™s Tesla Truck take. Anyone can offer a â€śhot takeâ€ť on current events, and darn near every media outlet did! But it takes a brave team (or just a very busy-with-other-work one!) to offer a â€ścold takeâ€ť weeks later. In our defense, we were trying to add something to CleanTechnicaâ€™s already-substantive coverage and reflections (e.g., this and this)
